Nile

The Nile flows through Sudan for 1,900 km — yet millions lack clean water The Nile flows through Sudan for approximately 1,900 kilometres. The Blue Nile descends from the Ethiopian highlands through Sennar and Kosti. The White Nile flows from Uganda through South Sudan and Malakal. They join at Khartoum. The combined river then flows north through Sudan’s dry core, past the ancient cataracts, through the Nubian Desert, and into Egypt. By volume, more than 80 percent of the Nile’s water originates in Sudan’s catchment — the Ethiopian highlands via the Blue Nile and Atbara — before flowing through or past Sudan entirely. ...

The Gezira model: one canal, a grid of laterals, and 880,000 hectares of irrigated farmland In 1925, a single canal changed the history of central Sudan. The Sennar Dam on the Blue Nile and the network of irrigation channels it fed transformed the Gezira Plain — a flat, semi-arid expanse between the Blue and White Niles — into one of Africa’s most productive agricultural zones. At its peak, the Gezira Scheme irrigated over 880,000 hectares of cotton, sorghum, and wheat, generating a third of Sudan’s export revenues and employing hundreds of thousands of families. The concept was simple: bring water to flat land that already had soil. ...

Khartoum Kosti Khartoum to Kosti: 320 km of navigable Nile — river freight costs 3× less than road haulage The Nile enters Sudan near Wadi Halfa in the north and flows south through Dongola, Khartoum, Kosti, and Renk before crossing into South Sudan — a journey of nearly 1,850 kilometres. For most of this distance, the river is wide, deep, and navigable. It passes through the heart of the country’s agricultural zones, connects its largest cities, and reaches populations that road infrastructure has never reliably served. ...
